X11模态对话框

Question

How can I create a modal dialog in X11 using Xlib?

A modal dialog is aa window that stays on top of other windows of the app (like transient windows do) and also refuses to give focus to other windows of the app.

In Windows, modality is also signaled by flashing the titlebar of the modal window when trying to steal the focus from it.

Thanks.

您需要设置_NET_WM_STATE属性（类型为“原子列表”）以包含_NET_WM_STATE，请参阅EWMP规范中对_NET_WM_STATE的引用 （还需要正确设置WM_TRANSIENT_FOR）
